Wouldn’t it be cool to have a little black hole in your office? You know, maybe as a trash bin. Or to move around the furniture. Or just as a kind of nerdy gimmick. Why can we not make black holes? Or can we? If we could, what could we do with them? And what’s a black hole laser? That’s what we’ll talk about today.

The Press and Teukolsky paper about the black hole bomb is here:

Physicists Say the Universe Wasn’t Born from the Big Bang. But How?

There have appeared many new scientific discoveries since that time, and many of them shake the foundations of the famous theory. It’s full of gaps and unanswered questions. So doesn’t this mean it’s not that perfect?

In this video, I’ll tell you: how many dimensions can the Universe have? What if the world was made of liquid? And most importantly, you’ll find out why the Big Bang theory can be wrong.

Gravitational Wave Scientists Pioneer New Laser Mode Sensor With Unprecedented Precision

Lasers support certain structures of light known as “eigenmodes.” An international collaboration of experts in gravitational waves.

Gravitational waves are distortions or ripples in the fabric of space and time. They were first detected in 2015 by the Advanced LIGO detectors and are produced by catastrophic events such as colliding black holes, supernovae, or merging neutron stars.
